The engine revs when idle and shuts down sometimes when am waiting at a stoplight. The diagnostic test done is not showing a problem as each time the car revs the communication cuts off from the cars computer. I have changed the air flow control valve also and the problem still persist. The cars computer was also checked and its working fine.
